I just bought a head unit for a hundred bucks (mainly because it plays CDs and not much else). I have the wiring harness for my car ('93 325i) and I connected that to the head unit. However...there are two larger gauge black wires coming out of my car that I had no place to connect to the head unit. So... I didn't connect them.
I turned the radio on, but all i got was static. I need some help. They want $60 (at LEAST) to install this thing.
here is a picture of the back of the head unit with the Unit's harness installed and the car's harness spliced up.
you'll notice two grey wires and with red and white tips on the left hand side of the picture. These are part of the HU's wiring harness. You'll also notice the two Yellow wires on the right side of the picture with the same tips. Additionally there's a black wire with a VERY DEEP female end. these wires were unused when I put the head unit in. I figured they were auxilliary.
There are two wires coming out of the car that i have issue with.
one is a thicker gauge black one that is part of the CAR-SIDE wire harness, but there is no place for it to attach on the HU' harness. The other is the same gauge and color, but has a circular tip with a little prong in the inside of it. This connects by itself to the bottom left corner of the factory head unit (if you're looking at the back of the head unit as though from inside the DIN port.
You need to go back to the store and ask them for a "BMW antenna adapter" The larger "deep black wire" is your antenna for that radio. BMW's have their own style of antenna lead, and need this adapter, then you wont have static.
The other black wire you talked about is probably your cd changer DIN cord, that won't be used in your new radio. Most BMW's come factory pre-wired for a cd changer.
The little red and white caps you removed need to go back on the yellow/gray wires. These are your RCA leads and will be used if/when you install an amplifier.
Hope that helps....

ok, i bought the adapter from tweeter today. I put it into my car...but now my head unit doesn't work. I put the old one back in...and that doesn't work either. What the hell happened??? I hope i only blew a fuse...
nope no lights no sound. Nothing at all. It's like I didn't even push power. I think I'm just going to throw in the towel, admit that I know nothing about car audio, and have Tweeter install it. They gave me a better quote than Best Buy. Hopefully they'll have the fuse i need (if I blew one).
By the way, I love the pic of Farley in your sig. "How many heart attacks does dat make for you?" "That would make da baker's dozen".
